Your first problem is that "learning" and "attention seeking" are somewhat at odds. If your color scheme is trying to get attention, by definition it's distracting, and you aren't going to be able to concentrate as well (and thereby learn).

If you want something not distracting, a clean, light-colored background (white, off-white, light beige, light gray) with a low-contrast color for a highlight (black, gray, navy blue, hunter green — not red) is somewhere to start.
